摘要:
A device for retracting edges of an incision in a surface to form an opening including: a flexible, tubular skirt having an upper end, a lower end, and a channel therebetween; a ring connected to the lower end of the skirt for maintaining the lower end in an open configuration and defining an exit opening to the channel; and an inflatable collar connected to the skirt and surrounding the upper end. The ring is designed to fit through the incision and remain under the surface when it is oriented parallel to surface. The collar, when inflated, maintains the upper end in an open configuration and defines an entry opening to the channel. During use, the ring is inserted through the incision and the collar is inflated while remaining outside of the incision, thereby drawing the skirt against the edges of the incision and retracting the edges of the incision to form the opening. The retracting device can be included in a surgical access port, which further includes a flexible sleeve connected to at least one of the inflatable collar and the skirt, extending the channel from the exit opening of the skirt to an open end of the flexible sleeve distal to the skirt. The device can include a light source in the vicinity of the exit opening.

摘要:
Systems, methods, and miniature instruments are disclosed for minimally invasive surgical procedures. A miniature surgical instrument can be inserted directly into a body cavity through a cannula in a way that a surgeon can insert his or her hand into the cavity through a separate minimal incision and use the miniature instruments. A miniature surgical system can include: a cannula having a hollow body configured to receive a miniature surgical instrument and a tether connected to the instrument; and a plunger sized to engage a proximal end of the body and including a conduit therethrough for receiving the tether. The system can also include the tether and the instrument. During use, the instruments can be quickly and safely removed from the body cavity to enable the surgeon to use his or her fingers, e.g., to manipulate tissue.

The present invention encompasses tools and a tool-holding retractor assembly. The retractor assembly spreads an incision and holds the incision open. At least one extension device, having a tool holder on one end, attaches to the assembly. The holder includes a selectively locking multi-axis adjustable mounting element adapted to grip a tool shaft. The mounting element acts as a universal mounting providing rotational and sliding movement of the tool shaft. The extension device adjusts to position the tool holder peripherally of the surgical field. Once the retractor is placed, the extension device provides full access to regions below the incision. The extension device allows the surgeon to chose the insertion point and insertion angle of the tool shaft.

The present invention provides a system and method for forming a side branch on a hollow vessel, such as the aorta. The side branch is preferably adapted to be connected to a connector conduit, but any other suitable use is also acceptable. The system comprises a graft including a side branch portion, and an applicator comprising a hole forming element adapted to form a hole in the wall of the vessel and an insertion element adapted to be inserted through the wall of the vessel, the insertion element comprising a retraction element adapted to enter into engagement with the graft. The hole forming element may comprise a cutting element adapted to cut a hole in the wall of the vessel, and a positioning element adapted to hold the position of the applicator relative to the vessel. The system further comprises a graft protection element adapted to prevent the graft from being damaged by the cutting element. In this case, the clamping element and the graft protection element may be the same element, for example, an expansion element, which may be expandable from an unexpanded state to fully expanded state and to a partially expanded state. The expansion element may be a balloon, which may be in the shape of a circular toroid, and may include a tension member that restricts the dimensions of the balloon. In addition, the expansion element may be an umbrella mechanism.
